It seem your current version "LF94510J.64T.0000.2009.0123.1105" doesnt have any BIOS ID's which is required to upgrading. Where '0000' should have any version number.I recommend using DOS environment when upgrading BIOS, this is the safe way flashing BIOS..so download file LF94510J.86A.0278.BI.ZIPhere. Extract all files on USB flash disk which is bootable flash disk. Run files executable on the command prompt and follow the instructions..

I followed the suggestion of changing the BIOS configuration to the recovery mode, however one thing was missing - it required a startup disk and I didn't have one. I then changed the BIOS configuration to the config (pins 2 & 3) mode, booted up and went to the BIOS/CMOS setup and a new menu tab appeared called "maintenance". I went to the advance tab and selected USB configuration and, instead of a blank screen, there appeared a selection for USB support and it showed disabled. I changed the setting to enabled and three more lines of information regarding USB came up, but required not further changes. I went to F10 and saved and exited and I now have me USB capability back.
